I love almost everything about it. It’s easy, it’s fast, it’s practical. Only thing I don’t like: it’s not air/liquid tight.The point of an alcohol wash is to slosh the bees around in alcohol, removing the mites. This can be hard to do when a fair amount of your alcohol leaks out during said sloshing. It leaks…a lot. I think with some minor adjustments, it could be perfect. It is very good, it gives accurate and easy counts. Just wish it was less messy and I would feel more confident if my alcohol levels were near at what they were, pre-slosh and know certainly I wasn’t having mites slip through with the lost alcohol.
